PHP Simple HTML DOM Parser caching multiple pages

Question

I am using PHP Simple HTML DOM Parser and using $html->load_file

include('simple_html_dom.php');
$html = new simple_html_dom();
$html->load_file('https://www.google.com/finance?q=goog');

the link below demonstrates a method to force caching of the content. I need to retrieve pages where the content changes depending on the last part of the url. Is it possible to modify the code below to force caching, for example, if I retrieve the following pages:

google.com/finance?q=goog

google.com/finance?q=wwwfx

google.com/finance?q=vigrx

Can I cache each one of those pages until the end of the session because I will need the page content repeatedly.

Caching PHP Simple HTML DOM Parser

function cache_get_contents($url, $offset = 600, $override = false) {
    $file = '/tmp/file_cache_' . md5($url);
    if (!$override && file_exists($file) && filemtime($file) > time() - $offset)
        return file_get_contents($file);

    $contents = file_get_contents($url);
    if ($contents === false)
        return false;

    file_put_contents($file, $contents);
    return $contents;
}

This is a lazy mans cache. Look into memcached. Or write code that looks at how old the file is and have it update the contents after n hours. — Carter
